CHARLES HOLLIWELL, OF BROADHEATH, ENGLAND, ASSIGNOR TO THE MER-GENTHALER LINOTYPE COMPANY, OF NEW YORK, N. Y.

MOLD AND CASTING MECHANISM OF LlNOTYPE-MACHINES.

SPECIFICATION forming part of Letters Patent No. 687,627, dated November26, 1901. Application filed May 28,1901. Serial No. 62,283. (No model Toall whom it may concern.-

Be it known that I, CHARLES HOLLIWELL, of Broadheath, in the county ofChester, England, have invented certain new and useful Improvements inMolds and Casting Mechanisms of Linotype-Machines; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in linotype-machines, moreespecially machines of the type represented in United States LettersPatent to Mergenthaler,No.436,53:2,dated September 16, 1890.

The object of the invention is to adapt the machine for castinglinotypes of ordinary type height, as usual, and also for castinglinotypes of less thanthe ordinary height to be used in a so-calledfudge or late-news attachment for printing-presses.

In linotype-machines a printing slug or linotype is formed in a slottedmold lying for the time being between a line of metal letter-matricesassembled temporarily against one side of the mold and the mouth of ametal-pot presented momentarily against the opposite side of the mold toclose the same and deliver the molten metal thereto. The height of theslug or linotype is determined by the depth of the mold from its frontto its rear face, and exact precision in height is obtained by a knifeacting across the rear face of the mold to trim the base of thecontained linotype flush therewith. In the operation of the machine themold is moved against the assembled line of matrices and the mouth ofthe pot advanced tightly against the rear face of the mold. A normal orordinary linotype.

stands type-high, and ordinary stereo-plates and stereo-turtles are asthick as type are high. It has become thepractice of late years 5 to fixlate-news linotypes in the stereo-plate or the stereo-turtle of anewspaper-press by means of a detachable tray adapted to hold themtype-high when it is fixed in the stereoplate or the turtle. This trayis known as a fudge-box. It is necessarily not deep enough to taketype-high linotypes, because the space for it in that direction islimited, so that fudge-linotypes-i. a, linotypes forlate newsare, as arule, only about half the normal height.

The object of this invention is to adapt a linotype-casting mechanism toproducefudgelinotypes whenever occasion demands more economically thanother so-called improvements for the same purpose have succeeded indoing. To this end I provide the machine with a mold of less than thenormal depth or thickness and corresponding with the height of thefudge-linotype, and I combine with the metal-pot an operating mechanismwhereby it may be advanced beyond its normal stopping-point to cooperatewith the reduced mold, and I also provide a movable knife adapted tooperate in connection with the low mold. The mouth of the pot ispreferably made longer than heretofore in order to enable it to reachthe rear face of the reduced mold-block. The means for varying themovement of the pot consist, preferably, in an adjustable rollerinterposed between the pot and its acting cam, this roller being eithermade with two peripheries of different diam- 'eters, either of which maybe brought into action at will, or combined with means by which itsrelation to the pot may be varied.

Referring to the accompanying figures, which are to be taken as part ofthis specifi- 8o cation and read therewith, Figure 1 is a sideelevation, partly in section, showing the potcam acting through thelarger roller, and thereby holding its nozzle in metal-tight contactwith the rear face of a fudge mold-block held for the time being by themold-wheel in the casting position; Fig. 2, a plan showing. the largerroller adjusted and locked to be acted on by the pot-cam 5 Fig. 3, aplan showing the smaller roller adjusted and locked to be acted on bythe pot-cam; Fig. 4, a front elevation of a mold-wheel, fudge-mold onit, and the knife for trimming the foot of the fudge-linotype cast inthe said mold; Fig. 5, a plan corresponding with Fig. 4; Fig. 6, a 5sectional detail plan illustrating the action of the foot-trimmingknife; Fig. 7, a rear elevation of the metal-pot cam-lever, the compoundantifriction-roller, and the locking device. elevation, and Fig. 10 adetail, all illustrating a modification of the roller and locking Fig..8 is a detail plan, Fig. 9 a side Ico device, while Fig. 11 is a detailplan, Fig. 12 a side elevation, Fig. 13 a side elevation, and Fig. 14 aplan, all illustrating a second modification of the roller and lockingdevice.

1 (shown in Fig. 1) is the mold for the print-- ing edge of thelinotype; 2, the row of matrices; 3, the mold-wheel; 4, its bush; 5, thehole in it through which the respective normal mold-block projects farenough for the nozzle of the metal-pot to make metal-tight contact withit; 6, the metal-pot; 7, the frame that supports it; 8, the pivot-rodupon which the pot 6 and frame 7 are moved forward by the cam and backby their own weight; 9, the cam-shaft turning in the direction indicatedby the arrows; 10, the cam that pushes the pot 6 forward; 11, a leverswinging by its top end from a pin 12, passed through it-,'and a pair ofrearwardly projecting lugs 13 13, fast on the metal-pot 6; 1t 14, a pairof cheeks fast on the pot-lever 11 and projecting to the rear to carry15, the axle of the antifrictionroller; 16, a rearwardly-projecting pinpivoted by its front end to the pot-support 7 and passed through thebottom end of the pot-lever 11 to hold a cushioning-spring 17 betweenthem. The mechanisms that impart the above-described linear and circularmotions to the mold-wheel 3 are notincluded in the figures, because theyare not modified by the present invention. The wheel is turned by anintermittently-acting pinion engaging in the gearing 18. All the partsabove mentioned are as heretofore.

The mold-wheel 3 acts only as a carrier of the mold-block and may, asfar as the present invention is concerned, be replaced by ablock adaptedto move rectilinearly from the casting to the ejecting position and backagain.

It is therefore referred to hereinafter asthe mold-carrier. The mold forthe printing edge of the linotype may be of any suitable construction,and the metal-pot may be moved rectilinearly instead of being rocked andby any suitable means.

19 is theimproved mold-block, and the slot 20 in it is the mold for thebody of the fudgelinotype 28. The construction of this block 19, as wellas the means by which it is held to the mold-carrier 3, is the same asheretofore, excepting that the width of the slot 20 is reduced and thatthe mold-block 19 not only does not enter the hole 5, but stands withits rear face at a little distance from the front of the saidmold-carrier, thereby establishing a clear space between them to makethe trimming of the foot of the said linotype 28 possible. The reductionin the width of the slot 20 is clearly shown in Figs. 1 and 4 at 31. Itextends from one end of the mold-block to the other and from the top ofit downward as far as the dotted line in Fig. 4.

21 is the nozzle of the metal-pot 6, duly lengthened to meet therequirements of the present invention. 22 indicates the usual metalports through it, shown. in Fig. 1 as registering with the slot 20.

23 21 are the two peripheries of the compound antifriction-rolleralready mentioned. The distance between the cheeks 14 14 is greater thanthe sum of the widths of the two peripheries 23 24 by a distancesufficient to allow of the compound roller being moved along the axle 15to make either periphery 23 or 21 run on the cam 10, the other peripherybeing then of course off it.

25'is a locking-piece pivoted on the lever 11 by the screw 26, and 27 isthe operative end of it. \Vhen the smaller periphery 23 is running onthe cam 10, the larger one 24 is between the said cam and a check 14 andoverlapping the former, as clearly shown in Fig. 3, so as to prevent thecompound roller moving along the axle 15 toward the opposite cheek 11.When the larger periphery 2 1 is running on the cam 10, the compoundroller is prevented moving along the axle-pin 15 in either direction byone cheek Hand the locking-piece end 27, duly dropped down between thelarger portion 2t of the compound roller and the opposite cheek 14,, towhich the said portion is then adjacent.

29 is the knife for trimming the foot of the fudge-linotype, and 30 isits cutting edge. In the Mergenthaler linotype-machine it is fixed tothe mold wheel guide 31, because that shares the to-and-fro motion ofthe carrier 3 between its front and rear positions.' As the knife 29 iswanted only during the time that the fudge mold-block 19 is in use, itis fixed by some device, such as a wing-nut 32, working on a screw 33,fast in and projecting from the block 31 and over which the knife ispassed, the crank 34 in the latter bearing against the block 31 to keepthe edge 30 in the proper position; but this knife may be fixed in anyconvenient position and to any suitable part, according to theconstruction and motions of the mold-carrier, provided that the cuttingedge 30 is held in the proper planet'. e., the plane of the trimmed footof the fudge linotype 28and. that the untrimmed foot is moved past thesaid edge 30.

When a normal linotype mold-block is in the working position on themold-carrier 3, it fills the hole 5, the rear face of that portion of itstanding either flush with the rear face of the mold-carrier or a littleto the rear of it. The length of the motions of the pot-nozzle 21 to thefront and back again must then be correspondingly normal or short, andto provide for that the compound antifriction-roller is adjusted on theaxle 15 so that its smaller periphery 23 shall run on the cam 10. When afudge-linotype mold-block 19 substitutes the normal one, the length ofthe motions of the potnozzle 21 to the front and back again must becorrespondingly longer, and to pro- -vide for that the said roller isadjusted on the axle 15 so that its larger periphery shall run on thecam 10.

The modification of the roller and locking device illustrated in Figs, 8to 10 consists in the distance between the cam 10 and the pe- IIOriphery of the roller 35being adjustable according to the distance whichthe nozzle 21 of the metal-pot 6 must be moved to the front to contactwith the rear face of the mold-block.

respective cheek 14, 38 being the locking piece, having offsets 39 39 tooverhang the respective cheeks 14 14 to prevent it being shaken out ofposition and small enough in diameter to be passed through the slots 37in front of the two blocks 36. When the locking-piece is in the positiondescribed and illustrated in Fig. 9, the roller 35 islocked in theposition to make the nozzle 21 contact with a fudge mold-block 19. Ifthe said piece be taken out of the slots 37 37, the weight of the pot 6will slide'the cheeks 14 14 rearwardly over the blocks 36 36 till thefront ends of the said slots and blocks are in contact and will keepthem so, so that the roller 35 will then be in position to make thenozzle 21 contac with a normal mold-block.

The modification illustrated in Figs. 11 to 14 consists in the roller 40being mounted eccentrically upon its axle 41, the amount of eccentricityestablishing the same difference between its radii as there is betweenthe radii of the two peripheries 23 and 24 described in connection withFigs. 1 to 7. Consequently either is substituted for the other upon thecam 10 by turning the roller through half a circle. Such turning isefiected from outside of the cheeks 14 by an external spider 42, fast tothe roller 40. Two of its legs 43 43, being those which coincide withthe respective major and minor radii of the roller 40,are prolonged,each having a notch 44 to embracea stud 45, projecting from therespective cheek 14, as shown in Figs. 11 and 12. The roller 40 is fastto the axle 41 by any suitable means and the spider 42 held fast to itby screws 46 passed through the same into the suitably-enlarged journal47. The opposite and smaller journal 48 is necessarily concentric withthe larger one, 47.

In the Mergenthaler machine the mold disk or carrier is commonlyprovided with two molds differing as to the size of their slots andlocated in the opposite sides of the center, so that one or the othermay be brought into action by adjusting the carrier through ahalf-revolution. When my invention is applied, one of these molds may beof the ordinary height for casting type-high linotypes and the other oflower height for casting fudge-linotypes, as shown in Fig. 1. Inasmuchas the knife for cooperating with the fudge-mold is located at the frontof the disk and the ordinary knife at the rear of the disk, there willbe no interference between them, and the machine will therefore beadapted for casting high or low slugs at will by simply bringing onemold or the other into operative position and by properly adjusting theoperin any form shown.

I believe myself to be the firstto provide a machine adapted for castinghigh linotypes with a shallow mold for casting low linotypes andadjusting devices by which the pot can be caused to operate with eithermold at will. I also believe myself to be the first to combine in alinotype-machine with a shallow mold a knife operating at the front ofthe moldcarrier to trim the base of the slug, thus admitting the use inone machine of both high and low molds and knives cooperating with therespective molds, and it will be understood by the skilled mechanic thatthese improvements may be varied in detail and embodied theequivalent ofthat herein I claim l.
